In\norder to satisfy the requirement that `static` items must implement `Sync`,\n`Singleton` implemented both `Sync` and `Send` unconditionally.\n\nThis allows for a bug where non-`Sync` types such as `Cell` can be used in\nsingletons and cause data races in concurrent programs.\n\nThe flaw was corrected in commit `b0d2bd20e` by adding trait bounds, requiring\nthe contaiend type to implement `Sync`.\n","aliases":["CVE-2020-36435","RUSTSEC-2020-0115"],"modified":"2023-11-08T04:03:44.661151Z","published":"2021-08-25T20:58:19Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2021-08-18T20:14:26Z","nvd_published_at":"2021-08-08T06:15:00Z","cwe_ids":["CWE-119","CWE-362"],"severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-36435"},{"type":"WEB","url":"https://github.com/RusPiRo/ruspiro-singleton/issues/10"},{"type":"WEB","url":"https://github.com/RusPiRo/ruspiro-singleton/pull/11"},{"type":"WEB","url":"https://github.com/RusPiRo/ruspiro-singleton/commit/b0d2bd20eb40b9cbc2958b981ba2dcd9e6f9396e"},{"type":"PACKAGE","url":"https://github.com/RusPiRo/ruspiro-singleton"},{"type":"WEB","url":"https://raw.githubusercontent.com/rustsec/advisory-db/main/crates/ruspiro-singleton/RUSTSEC-2020-0115.md"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2020-0115.html"}],"affected":[{"package":{"name":"ruspiro-singleton","ecosystem":"crates.io","purl":"pkg:cargo/ruspiro-singleton"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.4.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-fqq2-xp7m-xvm8/GHSA-fqq2-xp7m-xvm8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
